Engineering Review: The Filken X3 Outdoor Water Filtration System
1. Material & Structural Specifications: The SUS-304 Stainless Steel Housing
The first physical impression of the Filken X3 is its industrial durability. Unlike budget Fiber-Reinforced Plastic (FRP) filters that degrade and crack under continuous exposure to tropical sunlight, the Filken X3 utilizes a food-grade, passivated **SUS-304 Stainless Steel Vessel**.
The steel casing is 1.5mm thick, capable of handling operating pressures up to **6 bar (approx. 90 PSI)**, which is significantly higher than standard municipal tap water pressures in Johor Bahru or Kuala Lumpur (1.5 to 3 bar). This high pressure threshold eliminates the risk of vessel rupture during municipal mains pressure surges.
Inside this premium vessel sits the core filtration element: a bundle of **Hollow-Fiber Ultrafiltration (UF) Membranes**. The bundle features thousands of microscopic straw-like tubes made of polyacrylonitrile (PAN). Water is forced from the outside of these fibers into their hollow centers, physically blocking sand, rust scaling, and biological pathogens on the exterior surface.
2. Filtration Efficacy: High-Precision 0.01 Micron Separation
From an engineering perspective, the filtration rating is the most critical performance metric. Typical sand filters only filter down to 10-20 microns, letting fine colloidal clay pass through. The Filken X3 features an absolute **0.01-micron pore rating**.
This micro-fine pore structure performs high-precision separation, capturing 100% of suspended solids, clay silts, and rust flaking. Crucially, the 0.01-micron physical barrier intercepts biological pathogens including E. coli bacteria, Giardia parasites, and trace micro-algae that breed in communal reservoirs.
Despite this high-precision filtration, the X3 maintains an outstanding flow capacity of up to **2,500 liters per hour**. This high flow rate is achieved by the massive surface area of the bundled hollow fibers, ensuring that multiple showers, toilets, and laundry machines can run simultaneously without dropping household pressure.
3. Maintenance & Economics: Manual Flashing and Outright Saved Value
Maintenance of the Filken X3 is straightforward but requires consistent compliance. To prevent mud from compacting inside the hollow fibers, the system must be flushed once every week using the integrated multiport valve.
The weekly process involves a **1-minute forward flush** to wash away loose sand, followed by a **1-minute backwash** to purge trapped dirt inside the fiber walls. If this manual maintenance is ignored, the membrane suffers from irreversible compaction, restricting flow and reducing cartridge lifespan.
Economically, the Filken X3 represents exceptional value. Retailing around **RM 1,800 to RM 2,400 (including standard copper piping bypass installation)**, the system is sold as an outright purchase. There are no mandatory monthly rental fees. The internal membrane cartridge lasts **3 to 5 years** under standard municipal water conditions, with replacements costing RM 150 – RM 450 (prices subject to change, check with supplier) to RM 650 – RM 1,450 (prices subject to change, check with supplier), yielding massive savings compared to continuous brand rental contracts.

Frequently Asked Questions
Q1: Can the Filken X3 remove chlorine from the entire house water supply? expand_more
No. The Filken X3 utilizes an ultrafiltration membrane that physically blocks sand, mud, and bacteria, but it **does not contain active carbon**. Therefore, it does not remove dissolved chemicals like chlorine. Retaining chlorine in the home mainline is actually beneficial, as it prevents bacterial breeding inside your roof storage tank.
Q2: How often do I need to perform a backwash on the Filken X3? expand_more
We recommend performing a 2-minute backwash and rinse cycle **once every week** (or every 2 weeks at a minimum). In zones with high municipal mains silt or after water pipe repairs, backwashing should be done immediately to prevent sediment compaction.
Q3: What is the replacement cost of the internal hollow-fiber membrane? expand_more
A genuine replacement Filken UF membrane cartridge costs between **RM 150 – RM 450 (prices subject to change, check with supplier) to RM 650 – RM 1,450 (prices subject to change, check with supplier)** and is replaced once every 3 to 5 years, depending on water usage and backwashing compliance.
Q4: Will the Filken X3 cause water pressure to drop on my upper floors? expand_more
No, provided the membrane is backwashed regularly. Due to the massive surface area of the hollow-fiber design, the pressure drop across a clean Filken X3 membrane is negligible (less than 0.1 bar).
